Adding Potassium

Trying to go the dry fert route. Picked up a lb. of K2SO4. Been searching to try to find this answer but still not sure.

How many grams of K2SO4 would I have to add to 250 ml of water to equal the dosing recommendation (5 ml for 30 gallons) of Seachems Flourish Potassium? Bottle states that this dose raises potassium by 2mg/L.

I have been adding Seachems Flourish Potassium (along with other ferts) twice a week and it's working out very nice for my plants. I would like to duplicate this dosage using dry ferts.

Thanks in advance for any responses.


75 Gallon--Rainbow Fish Tank/Amano Shrimp
29 Gallon--Celestial Pearl Danios/Yellow Shrimp
20 Gallon--Ember Tetras/Orange Shrimp
10 Gallon--Chili Rasboras/Cherry Red Shrimp
